As big a talent as Beyoncé Knowles is, you sometimes wonder if there's enough of her to go round. Singer, actress, endorser of scented products, Beyoncé is the mistress of all she surveys, and not afraid to be thought a jack of all trades. Her recent recordings have contested that to be a big star, you also have to make a big damn album. Her latest one, I Am Sasha Fierce, is a double, testifying to both her work ethic, and also her knack of not alienating any portion of her potential market, catering both for fans of expensive R&B, and old school tearjerking ballads alike. Post-Crazy In Love, it's these latter songs that have been the most successful for Beyoncé - as much as we might conceptually like the idea of Sasha Fierce, it looks as if her rather softer alter ego (let's call her "Sasha Smooch") is winning out.
